I just want to know what everyone does when using an electric welder on their cars? I want to do a small job on the exhaust pipe using an arc welder. I know that on older cars prior to electronics that you just disconnected the battery and all was ok. With the modern electronics, is there anything else that needs to be disconnected prior to welding, such as the ecu or anything else???
I dont want to stuff up the electronics. :togo: |

I've welded on cars before with the battery connected. Just because you can do it doesn't make it a good idea. Disconnection of the battery is a very good idea as is a surge protector if you have one.
